SPECIFICATION forming part of Letters Patent No. 607,945, dated July 26, 1898. Application filed November 30, 1897. Serial No. 660,294. (No model.)

To all whom it may concern:

Be it known that I, FRITZ MUHLINGHAUS, a subject of the Emperor of Germany, residing at Barmen, Rhenish Prussia, Germany, have invented certain new and useful Improvements in J acquarddvlachines for Looms; and I do declarethe following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object to reduce the number of cards necessary for pattern goods, and the end is attained by using two separate cylinders, one for ground and the other for figure weaving, which carry their corresponding cards, both cylinders being moved independently of each other by means of a driving device which allows such a move} ment of the cylinders that both are simultaneously removed from the needles a like distance, but driven against them alternately weft by weft, or each cylinder can strike the needles a number of wefts in succession, according to the pattern, such operation being regulated by the machine.

The manner in which I prefer to carry my invention into effect is shown in the accompanying drawings, of which- Figure 1 is a side elevation of the improved jacquard-machine. Fig. 2 is a front view of the same. Figs. 3 to 6 are details of constru 0- tion. Figs. 7 and 8 show the working of the driving device for the cylinders. Fig. 9 is a modification of the machine with back arrangement of the driving device. Fig. 10 is a construction showing the device mounted on the head of the machine.

a denotes the jacquard-machine, of generally known construction, which is fitted with two need1eboards b in front, being arranged one above another and being fitted with needles and the necessary number of sinkers. In front of said needle-boards are arranged the cylinders c, the upper for the ground and the other for figure binding. These cylinders are not carried, as usual, by the batten, but are journaled in slides f f, respectively, which are guided at each side of the machine by suitable bearings e. The slides are moved to and fro in sucha manner that both are pushed simultaneously forward to remove by this operation the cylinders from the needleboards in a like way; but they are withdrawn alternately one by one as the pattern does this prescribe. For this purpose at the side of said slides is arranged a carriage it, being guided on bars 9 and receiving a to-and-fro movement by the batten cl, with which it is coupled by a connecting-rod As is shown in Figs. 3 and 4, the slides f f are provided with fixed hooks 70, each having its mouth directed to ward the back side of the machine. The carriages are fittedwith bolts Z, which by being moved forward engage said hooks and push the slides the same way in order to remove both cylinders from the needles. For the contrary movement of the slides they are provided with a second set of hooks m m, which are arranged as double-armed levers and can turn round a bolt n. The hooks m are placed in slots m in the slides. A spring 0, pressing on the short end of said hook m, causes the month, which is directed contrary to that of hook 70, to enter the slides, giving thus a free passage for the boltl on its back movement, so that the slide is not carried back and the cylinder can therefore not strike the needles. If, however, it is prescribed by the pattern, the slides are moved backward and the hooks m m cross the way of the bolts Z, so that they can beengaged by said bolts. This is effected by levers 10, which are arranged above and below the slides ff, so as to swing on bolts 19, and having a bladespring q, that acts on the hooks 'm m and presses them out of the slides when being moved up and down. For this purpose a cam-disk r is bolted to the machine, which is fitted with a rod 8, the ends of which are connected by cords s to double-armed levers t, journaled on the frame of the loom. The other ends of these levers have connection to corresponding sinkers If, and it will be easily understood that the sinkers when being raised by the knives by the known action of the cyl inders cause an oscillating of the levers 2, so that the cam-disk r engages the lower lever 10, which causes the hook m to be pushed upward, while its fellow hook escapes, as the upper lever 19, having connection to the lower one by a rod u, is likewise raised. The effect of this operation, which is illustrated in Fig. 7, is the back movement of slide f, carrying the figure-cylinder, that can now Strike the needles. In order to attain the same effect for the ground-cylinder, the cam-disk 7" allows the levers p to be pulled down bya spring 12, and the upper hook on is brought in engagement with the carriage and the lower hook is withdrawn to its normal position, the slide f is carried backward, and the groundcylinder can strike the needles, Fig. 8. Now in order that the carriage 71. can go forward again, though one of the movable hooks is in its way, the head of each of the hooks m 'm is curved and the spring-blade q of the levers p is of spring-like action, Fig. 5, so that the bolt can easily slip through.

The device thus described can be carried out in different modifications. Instead of lodging the same aside the machine, as in the present example, I can arrange the slides and their appertainings in a special frame 5, which can be mounted behind the jacquard-machine, the cylinders being then carried in frames 6, that have connection to the slides in the manner shown in Fig. 9 of the drawings. I can also arrange the slides on the head of the jacquard-machine, Fig. 10, driving the carriage, as before, by the oscillating machine-shaft ocby means of an an gle-lever g No battens are then necessary. The movement of the slides is transmitted to the cyl inders by double-armed levers 2, which carry them in their lower ends.

I am aware that jacquard-machines with two cylinders, one for ground and the other for figure binding, have been made before my invention, and I do not, therefore, claim such a machine broadly; but

.What I do claim, and desire to secure by Letters Patent, is-- In combination in a jacquard-machine having two cylinders, one for ground the other for figure binding, the arrangement of slides as f, f to carry said cylinders, a carriage as it, having bolts as Z, said bolts engaging stationary hooks 7c of the slides to push them in one direction and engaging alternately-movable hooks as m, m for the contrary movement of the slides, said movable hooks being acted upon by connected levers p with springblades and a camdisk 7" and connections therefrom to the sinkers of the' machine to turn the cam in the described manner as and for the purpose described and as shown in the drawings.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
